STANFORD, Calif. (AP) After gaining more than 6,000 yards the past two seasons, setting an NCAA record and finishing as the runner-up last year in the Heisman Trophy balloting, Christian McCaffrey was ready for his next challenge.

McCaffrey announced Wednesday that he will skip his senior season at Stanford and enter the NFL draft.

"I'm ready," he said. "My body is in the position it needs to be in to go out there and play at the next level. I've had some success in my college career."
